Temperature control and deposit automation systems, as well as systems for handling molds and cooling, are also coined as key defining features. More sophisticated machines offer control features through programmable logic controllers (PLCs), which allow the operator to program different recipes and automate changing settings for the different parameters.
History of Gummy Candies
Germany is the birthplace of gummy candy, where Hans Riegel invented the gummy bear in the 1920s using a simple kitchen and a hand-carved mold. This process was very slow, and the need for consistency required a high level of skill.
The deployment of mechanical molding machinery in the 1960s allowed for streamlined production without compromising quality. Early machinery employed steam heating systems along with gravity-fed mechanisms to fill various molds concurrently.
In the 1980s and 1990s, the introduction of demolding systems, precision pouring mechanisms, heating controls, and computerized controls increased the efficiency and consistency of production while minimizing waste.
Modern equipment used for the manufacture of gummies incorporates systems for digital supervision, automated supply of materials, and quality control, which guarantee the most favorable production conditions throughout the entire production process.
Types of Gummy Products
Traditional Gummy Candies
Standard formulations of gummy candies still include gummy bears, gummy worms, gummy rings, and other geometric shapes made with a gelatin base. Gummy products continue to maintain a hallmark chewy texture and physical moisture content of anywhere between 12-15%.
Functional Gummies
Nutraceutical gummy products include the likes of vitamins, minerals, herbs, and other pharmaceutical compounds while still tasting good and feeling good to chew. These products offer challenges and thus require specialized procedures to maintain external and internal ingredient stability, with some requiring alternative gelling additives.
Sugar-Free Versions
Sugar-free gummies with reduced caloric value made by the use of sugar alcohols, stevia, and other sweeteners, aided by alternative sweetener systems, are another product of bone gelatin. These formulations also maintain a chewy texture, but require specialized equipment for cooking texture procedures.
Specialty Versions
Custom gummies can incorporate the likes of different colors, unique shapes, stacked, layered designs, and even coatings. These specified products are made to have certain characteristics and require advanced processing steps to achieve ideal molds.
Understanding Gummy Making Equipment
Machine Classification
Gummy manufacturing equipment can be categorized as laboratory-scale, mid-scale, or industrial based on automation level, complexity, and production capability. Laboratory-scale units range from 10-50 kg per hour and are designed for research and development purposes.
Mid-scale production machines are designed for small to medium manufacturing operations, handling 50-200 kg per hour. These units often feature modular designs enabling capacity expansion through additional components.
Industrial-scale systems surpass 200 kg per hour and integrate fully automated processes from ingredient handling to packaging. These machines require significant capital investment but are the most cost-efficient for per-unit production.
Selection Criteria
Machine selection relies on production volume goals, available floor space, budget, and utility connections. Another important factor is product mix as some machines are designed to easily manufacture a range of gummies, while others specialize in a limited variety and are more efficient.
Energy efficiency while maintaining output quality is becoming increasingly important. Modern machines incorporate improved insulation, variable speed drives, and heat recovery systems, all of which minimize operating costs.
Key Components of a Gummy Maker Machine
Mixing Systems
The mixing system integrates multiple ingredients to form a consistent gummy base. High-efficiency mixers use specially designed impellers that optimize complete ingredient incorporation with a minimum of air incorporation, which can lead to defects.
Temperature-controlled mixing vessels offer optimal heat retention for specific and blended ingredients. Some systems have incorporated a vacuum function that can aid in air bubble removal, improving clarity for the final product.
Heating Elements
Devices within the system offer specific temperature ranges that require precise and reliable setpoint values. Steam heating provides fast response and uniform heat distribution, while electric heating offers better accuracy and ease of installation.
Switching to different product formulations calls for rapid temperature changes, which can be done using heat exchangers. Some advanced systems includes multiple heating zones to adapt different process parameters for different production stages.
Depositing Mechanisms
Automated depositing systems accurately and evenly distribute the gummy mixture to all designated molds. Use of volumetric depositing assures consistent product weights while temperature-controlled depositing heads mitigate the risk of premature gelling during the molding.
Modern systems use servo-driven mechanisms for precise accuracy in timing and positioning for depositing. Some units have multiple depositing heads to improve production rates or enable the manufacturing of multi-colored products.
Gummy Making Machine: Functions and Features
Process Control Systems
Modern gummy bear manufacturing employs programmable logic controllers (PLCs) for full automation of the production line. Such systems allow the operator to save several different recipes, supervise critical parameters, and make changes automatically and in real-time to maintain the best possible settings.
Human-machine interfaces (HMIs), handheld controllers simplify the control of complex operations pertaining to process automation by presenting alarms, status of processes, and production figures in a user-friendly manner. The use of touch-screen interfaces makes the running of the operations quite simple while allowing deep parameter settings for changes to be made.
Quality Monitoring
The integrated quality control systems outline the aspects of quality that should be checked during manufacturing processes, such as weight monitoring, to ensure the products are the same size. There also exist temperature sensors to ensure that the correct processing conditions are adhered to.
Some vision systems are integrated into the machines that check the products for color uniformity, shape accuracy, and surface defects. Monitoring systems that do not conform to the required standards are excluded and automatically collect data for subsequent processing.
Safety Features
Safety systems incorporating emergency stop, guard interlocks, and automated safety sequences are deployed to safeguard the operators and the equipment. Features that safeguard the operator make cleaning, maintenance, and the removal of the equipment simpler, also ensuring that no contamination risk is introduced.
When dealing with systems that have flavoring alcohols, some need to be explosion-proof. Some need to make sure the correct conditions, such as temperature and humidity in the production area, are adhered to.
Auxiliary Equipment in Gummy Manufacturing
Ingredient Handling Systems
Automated handling of ingredients boosts accuracy and consistency while minimizing labor needs. Gelatin, sugars, and other ingredients are kept in bulk storage systems set to the proper storage conditions.
Ingredient measuring systems are capable of weighing ingredients with an accuracy of ±0.1% of the target weight. Some systems integrate loss-in-weight feeders to add ingredients continuously during the manufacturing process.
Utility Systems
Compressed air systems serve dual purposes of powering pneumatic actuators and serving as plant air for cleaning operations. Filters and moisture removal devices must be in place to comply with food-grade standards.
Process heating requirements are supplied with steam-generating systems. Steam quality, for equipment scaling and product contamination protection, requires low dissolved solids content.
Water dealt with filtration, softening, and chlorine removal must be constantly monitored to provide consistent quality for product formulation and cleaning operations. Local water conditions strongly determine the system’s effectiveness.
The Gummy Production Process
Recipe Development
Achievements in gummy manufacturing start with balanced recipe development that considers taste, texture, appearance, and shelf-life stability. Depending on the required firmness, gelatin concentrations will be within 6% to 10%.
Most formulations contain 40-60% total sugars. The formulation’s sugar content will also dictate the texture and sweetness. The proportions of sucrose to corn syrup will impact the texture, processability, and overall characteristics of the final product.
Use of citric acid or other acidulants can be employed to adjust pH, which in turn will impact gel strength, flavor and odor perception, and color stability. For most gummy formulations, optimal pH is usually within 3.0-4.0.
Batch Preparation
The initial step involves the blooming of gelatin, which is the process of dry gelatin absorbing water to reach a hydrated state. This process takes on average 10-15 minutes to complete at a controlled temperature.
Sugar dissolution is performed in a separate vessel and involves adding water to the sugar. By heating this mixture, a clear syrup is generated. Caramelization and complete dissolution need to be managed separately to prevent overheating.
Addition of flavoring and coloring is done at controlled temperatures to preserve the stability of the ingredients and reach the desired intensities. This is especially true for heat-sensitive ingredients which demand strict temperature guards while blending.
Mixing Ingredients for Gummy Candies
Hydration Techniques
Proper hydration of gelatin is critical in achieving optimal gel strength and texture characteristics. Cold water hydration followed by gentle heating is ideal for attaining maximum gel formation.
Mixing intensity influences hydration efficiency. Optimal mixing intensities that accomplish adequate hydration and promote some degree of air incorporation. The entire hydration process easily has its intensity modified via variable-speed drives.
Ingredient Sequencing
The addition order affects product quality and efficiency in processing. As a rule of thumb, hydration of gelatin is done first, after which, sugar syrup is added followed by flavoring and coloring agents.
Ingredient addition requires temperature management to avoid premature gelling and ensure complete incorporation. Some formulations are dictated by critical timing to achieve maximum results.
Quality Parameters
The viscosity of the mixture indicates the incorporation accuracy and the ability to deposit, which affects the accuracy. Tracking the viscosity improvement means streamlining operations towards consistent product quality.
Oversight of temperature ensures the mixture is optimally processed. Gelatin may degrade at too high a temperature, which is unacceptable. Supercritical temperatures may result in suspension of some ingredients due to incomplete dissolution.
Heating and Cooking the Gummy Mixture
Temperature Control
Accurate temperature control ensures no gellan degradation occurs and full ingredient dissolution is achieved. Processing temperatures are maintained between 80-95°C for optimal formulation.
Overheating is avoided by mean rate control, which could lead to color or textural changes. Elevation of temperature can cause overheating of the system as well as poor mixture distribution.
Mixing During Heating
In the heating phase, mixing is maintained to avoid temperature differentials as well as ingredient accumulation in the bottom. Scraper stocks are constructed so that they can mix the products without allowing the mixture to settle down on the walls of the vessels to ensure good heat exchange.
Different stages of the process can be managed with different mixing speeds, provided that they can be varied. Higher speeds can be used during the last phase of temperature adjustment.
Vacuum Application
Vacuum portions can be used to control the levels of air and foam that are allowed to enter the vessels. This changes the foam and transparency of the products. For different formulations, the optimal level is 15-25 inches of mercury.
This subsection deals with the minimum and maximum levels of the vacuum that can be held. There are limits to how quickly the vacuum can be introduced; if they introduce the vacuum too slowly, the mixture that is inside is at risk of foaming. This is the same reason why pressure needs to slowly be equalized to prevent foaming.
Molding and Cooling Gummies
Mold Selection
Mold materials impact thermal conductivity, demoldability, and labor. Silicone molds are thermal cycle resistant and are easy to demold.
Mold design and practices include cavity proportions—size dimension, shape complexity, and draft angles that promote easy removal of the product. Efficient mold design and manufacturing maintain uniform product shape and minimize excess material.
Depositing Accuracy
Depositing systematically achieves product uniformity and eliminates overflow or underfilling. Modern depositing machines have an accuracy of ±2% of the set product weight.
A temperature control system must be in place to prevent premature gelling of the product in the depositing system while filling molds correctly. Thermosensors should be deployed to monitor the temperature of the mixture in the depositing system.
Cooling Parameters
Final product texture and appearance are dependent on controlled rates of cooling. Surface defects may arise from rapid cooling, while slow cooling increases cycle time.
The design of the cooling tunnel should allow all molds positioned in the tunnel to experience the same temperature. Air circulation systems promote uniform cooling rates irrespective of the product position in the cooling zone.
Improving Gummy Production Efficiency
Automation Integration
Automated systems enhance production efficiency and consistency, while reducing labor requirements and cycle times. Robotic mold handling systems both “pick” and “place” molds automatically, eliminating manual lifting and positioning operations.
The horizontal collaborative production systems, integrated production lines, connect individual process steps to create an uninterrupted production flow. Such systems integratively reduce handling between processes as well as contamination risks.
In this section, process optimization focuses on scheduling changes involving the utilization of equipment. Equipment utilization in terms of scheduling can be enhanced with a well-planned, structured sequence of operations leading to a 15-20% overall equipment effectiveness.
Business efficiency can be integrated with equipment reliability in the formulation of preventative maintenance programs. Planned intervals, which are generally unbalanced, based upon operations and production volumes, can assist in the forecasting of parts renewal alongside stringent unplanned downtime.
Reduction of waste can be achieved through the precise NASA-like ingredient metering systems, which ensure raw material accuracy at around a 0.5% threshold. Automated systems, in this case, provide ingredient accuracy figures of ±0.5% of target values.
The waste reduction per the company performance is achieved through sophisticated untargeted product systems, which are designed to excel in off-specification items. Such systems can excel around 10% production during uncompromised quality thresholds.
Integrating a Dosing System
Precision Requirements
Achieving accurate dosing optimization prevents material waste and ensures consistency in product weight. Modern dosing systems achieve repeatability to within ±1% of target weights over several production cycles.
Calibration procedures verify and enable adjustments within set dosing thresholds. Regular calibrations ensure that drift does not occur, which may compromise product quality or yield calculations.
System Integration
Integrated dosing systems interact with process control systems to synchronize operation and control deposition of material with mold positioning. Such integration eliminates waste of product and optimizes mold fill.
Equipped with variable dosing options, one piece of equipment can be used to manufacture several sizes of a given product. Features that enable rapid changeovers reduce downtime during formulation changes.
Maintenance Considerations
Regular dosing and ingredient measurement accuracy are preserved with automated cleaning systems, which eliminate allergens or ingredient accumulation. Automating cleaning systems minimizes equipment maintenance time while enhancing overall cleaning safeguards.
Regular maintenance is streamlined with improved system access, reducing process downtime. Modular system designs allow rapid component swaps without system disassembly.
Utilizing a Cooling Tunnel for Quality
Temperature Control
Cooling tunnels streamline the temperature reduction process, optimizing gel formation while minimizing the production cycle time. Gradual, multi-stage cooling prevents thermal shock.
Air distribution systems circulate air to prevent uneven cooling across product positions. Balanced air distribution prevents the formation of ‘cold spots’, which can lead to extended cooling times.
Controlled ranges of humidity, typically 45-55%, prevent surface moisture loss, which, if excessive, can lead to product skin formation or internal texture defects.
Weather conditions can affect product quality. Therefore, humidity control systems are designed to operate within external conditions to ensure consistent, reproducible product quality year-round.
Defect-free can be achieved by maintaining a constant flow, which prevents product damage. Automated flow control allows modification of cooling times for different product formulations through adjustable belt speeds.
Maximized cooling efficiency while maintaining product circulation prevents product sticking. Maintaining adequate distance between individual products allows maximizing tunnel capacity.
